QUESTION 53A corporation has a Cisco Unified Wireless Network that has been deployed for voice coverage. The wireless data rates have been tuned to mandatory rates of 18 Mbps and 36 Mbps. Some wireless clients have been experiencing drops streaming multicast video while moving throughout the building. What is the cause of the drop in video?

A. Clients are roaming at lower data rates and are not maintaining 36Mbps connectivity.B. Clients are not roaming due to coverage. This is causing the multicast data to drop due to the client re-associating often.C. Clients are connected at 18Mbps; however, other clients are connecting at 12Mbps and are causing the multicast video to degrade.D. Clients are maintaining a 12Mbps rate and cannot receive the stream at 18Mbps.

Answer: A

QUESTION 57A customer called into the support center with a problem ticket that involves wireless clients having to reauthenticate when they are walking around their office. After further investigation, it was discovered that the customer has two controllers in an N+1 deployment. Which action must the engineer take to troubleshoot the issue?

A. Verify that the wireless controllers are in the same mobility group and that the access points are all on the primary controller.B. Under the SSID, make sure that 802.1 Iris configured and running for the clients.C. Make sure that the SSID has the authentication set to 802.1x with Cisco Centralized Key Management so the data clients can roam seamlessly.D. Verify the access points are spread out between the primary and secondary controller and that the controllers are in the same mobility group.

Answer: D

QUESTION 58A customer has implemented a wireless network that requires tuning for High Density applications utilizing the RX-SOP feature. They are experiencing a high noise floor (average of -65 dBm) and expect that to decrease significantly. A sampling of radios determine that most Access Points have neighbors on the same channel at a power level of -75 dBm. Which value should the customer use to start tuning RX-SOP?

A. -60 dBmB. -65dBmC. -70 dBmD. -75 dBmE. -80 dBm

Answer: C

QUESTION 59A client reports that video is not streaming. The administrator determines the client is connecting at a data rate of 12 Mbps and is trying to stream to a valid multicast address on the network. What three items should the administrator check next to troubleshoot the issue? (Choose three)

A. IGMP snooping is turned off because the client cannot request to join a group, only access points can.B. Video-stream for the multicast video is configured in the controller.C. WLAN has been set for a QoS value of Platinum.D. WLAN has been configured to allow multicast-direct to work correctly and multicast- direct has been enabled globally.E. WLAN has been set for a QoS value of Gold.F. RTSP is used to stream the video due to wireless multicast not using acknowledgements.
